To add:
Kanter was 11th in minutes (total and per game) over the playoffs for the Celtics.
I believe we all kind of agreed that we had a core of 7 guys that had proven themselves during the regular season (Tatum, Walker, Brown, Hayward, Smart, Theis, Kanter - in that order). If I were Kanter it would feel as a smack in the face.
I admire his composure and professionalism in how he dealt with that.
